-----------------------------------
Hi [~surendrasingh],
I did some digging into the history, as the asymmetry between
FileSystem#getQuota and HdfsAdmin#setQuota seemed intentional. Sure enough,
there's a discussion on HDFS-3000.
It sounds like we want to expose the HDFS-specific functionality in HdfsAdmin
via a REST interface. However, we need to do this without expanding the
FileSystem interface, since the HdfsAdmin functionality is HDFS-specific. So,
we need to define a separate WebHdfsAdmin separate from WebHdfsFileSystem. The
server-side functionality can still be implemented with the same NN and DN
servlets.
We also need to document these WebHdfsAdmin APIs specially, perhaps in a new
page that separates them from the FileSystem APIs.
